RELEASING DOOR-HANGER.

To all whom it may concern: Be it known that I, JOHN L. RIFER, a citizen of the United States, residing at ortland, in the county ofMultnomah and State of Oregon, have invented Certain new and useful Improvements in Releasing Door- Hangers, of which the following is a specification.

My invention relates to means for controlling the operation of a sliding door, and has particular reference to the door of a railway box car.

Generally speaking my object is to providd' a box car door of greater reliability and convenience of operatlon than the doors usually employed. To this end my aim is to providea door with manually operated means for lifting the door clear of the track.

on which it slides, and in thus-raising the door to interpose a plurality of anti-friction rollers between the door and said track.

A further object is to provide means for independently operating -the door mechanism either from the outside or inside. And finally my aim is to provide means for looking the door in position, so that it can only be moved through the medium of said manually operated lifting mechanism.

The objects and features of my invention are clearly set forth in the following description and illustrated in the appended drawings, of which:

Figure 1 is an outside elevation of the body of a box car embodying my invention, Fig. 2 illustrates, in perspective, the inside surface of a box car door, and Fig. 3 is a cross-sectional view substantially through the center of the door-mechanism. i

The door a rests on the sill of ear platform I). It is mounted to slide along the outer surface of the car side-wall 0, and is guided by suitable clips or rails a, 6. The lowercenter portion of the door is removed, and the openingor chamber thus created ison the outside closed by a sheet metal cover'd. On this cover I mount a pair of studs e, and on each of these I journal a pair of arms f, the opposite ends of which support an antifriction, roller 71.- The inner ends of studs e are fixed in a supporting plate 2', secured on the inner surface of the door. Spacers 9 may be employed to retain arms f in trans verse alinement, or said sleeves and arms may be combined into a solid frame. On shafts j of the rollers I journal two sets of Specification of Letters Patent. V Patented 1\Ia,y 28,1912. Application filed February 14, 1912. Serial No. 677,620.

links is, Z, which extend upward, their upper ends being journaled on a common fulcrum rod m. Said rod serves as support for a pair of pendent frames, one short frame '12 and one longer frame 0. On the outer surface of cover-plate d I fulcrum a hand-lever p, made with an arm g, which extends through said cover-plate and engages the lower extremity of a perforation r of pendent frame n. On supporting plate 71 I journal a second hand-lever 8, made with an arm t, which projects through the plate and engages the lower end of pendent frame 0.

Figs. 1 and 3 show the door resting on the car-sill, which is provided with a series of pockets u adapted to receive projections 'v of the door. Said pockets are spaced in any suitable manner to retain the door in a closed, partly opened or completely opened position. When desired to further open or close the door, from .the outside, hand lever p is raised, causing arm 9 to de ress frame n, which inits turn acts 'upon ulcrum rod m and links 70, Z to swing roller frames f on studs e, whereby rollers h are caused to engage the car sill, and whereby the door is raised until projections o of the door clear pocketsu. As pendent frame 0 is made with theelongated perforation w, the depression of the roller mechanism and consequent lifting of the-door take place without disturbing the position of hand-lever s. In

the same manner the door can be lifted and released from the sill from the inside of the car by raising hand-lever 8, see Fig. 2, without disturbing the setting of hand-lever p,

the perforation r of pendent frame at being also elongated so that said frame may descend without depressing arm gs of said lever p. A plate a: may be introduced to guide the mechanism mounted on rod m in the upper part of the door chamber, or said plate a: may be combined with supporting plate a to'form a complete cover corresponding to outside cover d.

From the foregoing descriptionit is made clear to those versed in the art, that the antifricti'on rollers are thrown into action by lifting the door either from the inside or the outside by means of either hand-lever, and how simultaneously the door is released from the sill of the car.

As indicated at 1 Fig. 3, I may introduce .a pad-lock or other suitable means for lock- 4 be operated by trespassers to move the door, and it is obvious that similar locking means may be used in connection with lever s- A box-car door is usually sealed before leaving the place of shipment, but in cases of doors that do not thus become sealed, it is necessary to provide additional locking means, inasmuch as a trespassing party may lift the door bodily until projections 21 clear pockets u, and then slide it along on said projections. lowing manner. From the door chamber extends a perpendicular groove 2 terminating at the top in a smaller chamber 2. A link 3 journals. on rod m, its upper end operatively connecting with a bell crank 4:, and the latter is made with an eccentric cam portion registering with the bottom of upper guide-rail 6.

By referring to Fig. 2 it is readily seen,

I that the raising of hand-levers to lift the door draws cam 5 away from rail 6, while said cam, when the door rests on the sill, stands so close to said rail that it is not possible to lift the door, bodily sufliciently to disengage projections 11 from pockets In conclusion I wish to state that, while I principally aim at providing a door mechanism for a box car, my device can conveniently be used on other structures such as barns or store houses.

- The pockets u may be so spaced, that the door can be locked in'place at any suitable point. The door may for example present a small opening for ventilation, as shown in Fig 1, and still be locked firmly in place.

I claim:

1. In a sliding door, the combination with a door-frame. and means for guiding the door relative to said frame; of a plurality of anti-friction rollers pivotally mounted in a cavity of said door; manually operated means for independently actuating said rollers from either side of the door, whereby said rollers are depressed and caused to engage the sill of said door frame and whereby the door is simultaneously lifted clear of the door-sill; and means actuated by the lifting of the door for disengaging the door from the sill to permit of sliding motion and actuated by the lowering of the door for again locking the door against sliding motion on the sill.
